Firestore DevTools

A browser extension that adds a Firestore panel to the browser DevTools and shows what a page is doing with Cloud Firestore — the queries, the document reads, the listeners and the writes — with the collection or document each one touches as its title. The Network tab can only show you HTTP requests, which is the wrong unit here: one listener's request and its responses travel on two different requests, and neither of them is named after anything you wrote.
